We Can Produce Three Type Seals R4 Inch Ball Bearings:
1.Open bearings dissipate heat more efficiently than shielded and sealed bearings.
2.R4ZZ Shielded bearings block out dust and other contaminants, but do not dissipate heat as efficiently as open bearings.
3.R4-2RS Sealed bearings block out dust and other contaminants better than open and shielded bearings, but retain the most heat.
